Heat recovery ventilators (HRV) constantly supply fresh air
to provide a healthy indoor environment by reducing odors and and indoor
pollutants, such as radon, formaldehyde, tobacco smoke, nitrogen dioxides,
carbon monoxide, and pesticides. Energy recovery units constantly bring
fresh air into the home while exhausting like amounts of stale indoor air at
the same time.
The recovery part of the ventilation means that the hot or
cold energy in the air (depending on the season) is extracted from the
indoor air before it is exhausted and transferred to the incoming air, so
that there is little energy lost.
Heat Recovery Ventilators use separate blowers to constantly
supply incoming fresh air while exhausting outgoing stale air. The
heat-exchange core transfers heat to fresh air without mixing the
airstreams. The damper automatically stops cold air for defrosting.
The efficiency of heat recovery ventilation became a
necessity due to increasing heating costs. Before the '70s, we happily
cranked up the thermostat when the house felt chilly. Once heating costs
went through the roof, though, we all put on sweaters and started looking
for ways to save. With up to 40 percent of our heating dollar going to air
drafts, sealing homes began to seem like the best defense against high
heating bills.
Unfortunately, those heat-sealing upgrades -- tight windows
and doors, insulation and vapor-barrier improvements, modern siding and
caulk for every crack through which air might pass -- while making the home
thermally efficient, sealed in a plethora of toxins, creating what's often
referred to as "sick building syndrome."
It turns out that those heat-robbing drafts played an
important role in the ecosystem of the home: they provided fresh air to
breathe. Thus the birth of home ventilation air exchangers.
HRV vs ERV
Heat recovery ventilators (HRV) will transfer temperature
only from the high temperature air to the low temperature air. Energy
recovery ventilators (ERV) transfer both temperature and moisture. Since
transferring both temperature and moisture has benefits in both winter and
summer, ERV's are a better choice in all but the most northern colder
climates for providing year round fresh air to the home.
Heat recovery units can be installed in an existing home, as
well as a new home, and are an integral part of the heating and air
conditioning system. HRV systems can work with any forced air system
equipped with a blower and duct system. It can also be used with non-forced
air systems (floor heat coils, for instance) as an independent system.
To maximize the air quality, you can keep your home closed
year-round and operate the HRV system constantly, efficiently producing a
fresh and secure environment.
Heat recovery ventilators should be serviced about every six
months. The simple procedures are fully described in the manual provided
with each unit. These maintenance procedures can be completed by you or your
contractor, if you desire.
